Abstract
A thiosulfate sensor having an electrode assembly including a sensing electrode including electrochemically deposited metal, a counter electrode, and a reference electrode is described. The thiosulfate sensor further includes an electrolyte chamber including an electrolyte solution therein, the electrolyte chamber receiving the electrode assembly through a first opening to immerse the electrode in the electrolyte and an electrolyte chamber porous membrane covering a second opening, where the porous membrane is configured to receive a flowing fluid therethrough to allow the detection of thiosulfate in the flowing fluid.
